Re-evalutating weights

I feel like I have jumped up to far on my weights, or going to heavy. I need to do my exercises with proper form, for them to be effective, but I have been using such heavy weights, that my form has not been good, so I am checking out my weights I am using, and going lighter on some, so that my form is good. Anyways here are my workout stats for back, biceps, and trapz:

Back

Bent Over Bar Rows

10 easy reps- 45 lbs
6 slightly heavier reps- 85 lbs
3 heavier reps- 130 lbs
4-6 heavy reps to failure- 170 lbs- 4 reps- they weren't complete reps
4-6 heavy reps to failure- 160 lbs- 4 good reps

One Arm Dumbell Rows
